IMPROVEMENT IN PUMPS.

Specification forming part of Letters Patent No. 37,383, datedrJanuary 13, 1863.

Toutll whom it may concern:

-Be it known that I, FRANCIS SQBURT, of Mount Pleasant, in the county of Henry and` State of Iowa, have invented anew and Improved Pump and I do hereby declare that the following is a full, clear, and exact description ofthe same, reference being had to the accompanying drawings, making a part of this specification, in which- Figure lfis a vertical central section of my invention, taken in the line a: w, Fig. 2; Fig. 2, a vertical. central section of the same, taken in the line y y, Fig. 1.

Similar letters of reference indicate corresponding parts in the two figures.

This linvention-relates to an improvementin that class of pumps which are submerged, and elevate the water to the top of the well through a tube. i

The object Aof this invention is to obtain a simple, eicient,- and economical? pumpef thel class'specied, and one that will not be liable to get out of repair or become deranged by use.

The invention consists in the employment or use of a reciprocating piston in connection with a sliding valve placed'in a compartment in the pumpchamber, and provided with open- Y ings and arranged in such relation with induction and eduction openings in the pump-chamber as to effect the desired end. To enable those skilled in the art to fully understand and construct my invention, I will proceedl to describe it. A represents the pump-chamber,which may be of rectangular form, and is provided with a vertical tube, B, which has a nozzle or spout, B', at its upper end, and also has a piston-rod, C, passing through it.. To theilower end of the pistonrod C there is attached a piston, D, which works ina compartment, E, in the pumpchamber; said 'compartment being formed by a vertical partition, F. This partition also forms a smaller compartment, G,.in which a valve,

vH, is placed, having two openings, a a', in

leach side'of it, and two chambers, b b', which are open at their ends, as shown at c c, said chambers being divided by a partition, d.- The valve H is of rectangular form, and isallowedlto slide freely up and down in the cornpartment-'G, whichV communicates with the larger? compartment, E, by passages e e atA the upper'and'lower endsof the'partitiony F, as shawn inflig. `1.

I is a water-passage, which is made inone side, and the'top of the chamber A, as shown in Fig. 1. The'lower end of thisv passage I communicates with the-tube at its lower part, and the lower end of .said passage communicates with the valve-compartment G when the valve H is raised, but said' passage is closed at-its lower.. end whenl the valve is down, the partition d covering it, as shown in Fig. 1. The piston D has la hole, f, made through it to admit of the waste-water from the tube B when the pump is stopped,thereby preventing the freezing up of the tube B in winter.

The operation of the pump is as follows: The chamber- A is submerged at the bottom of' the well or* reservoir, or nearly submerged,-

,and when tlie piston D 'rises a suction is -formed belowit and the valve H falls in its compartment G, and the water passes through induction-holes gv y in the'sides of the chamber.' and through the lower holes or openin gs, ai a', in the valve and lthence through the lower chamber, b, of the valve into the compartment E, underneath the piston, as indicated by the arrows 1. During this movement of thepiston .the Water above it is forced up-through the tubeB and out through the nozzle B'. Dur- ,ing` the downward movement of the piston the valve H is forcedupward in itscompartment G, and thelower end of the passage I is thereby opened and the water below the piston is forced through the passage I, upV

into and .through the tube B and out at the nozzle B'. During the downward movement of the piston the induction-openings g' are closed by the valve H, and the upper openingsa, are in line with induction-openings g g in the sides of the chamber A. AAs the pis ton descends, therefore, asu'ction is produced in the compartment E above it, and the water passes through the induction holes or openings g" into the chamber b of the valve, and4 thence into compartment E, said water being -forced up through tube B, when the pistonl again ascends the valve H, covering the holes g g,when it descends under the upward'movement of thepiston. Thus -by this very simple arrangement an eicient pump is obtained,

land one which may be constructed at a' small cost without the liability of getting out of re-- pair or becoming deranged by use.

, Having thus'fully described my invention,

what I claim as new7 and desire to secure by said chamber, all being constructed and ar- Letters Patent', is ranged as and for the purposes herein set;

The combination of the piston D and the forth. slide-valve H Working in separate compart-y g ments E l in Ahe pump-chamber A, in conneo- FLANCIS S' BUND' tion with the tube B'and the Water passage I Witnesses in the side and top of the chamber A, and the P.
